Question

我已经使用nginx和乘客在amazon ec2实例上部署了我的应用程序，并且在我调用fd_set input_set; struct timeval timeout; int ready_for_reading = 0; FD_ZERO(&input_set); FD_SET(0, &input_set); timeout.tv_sec = 5; timeout.tv_usec = 0; ready_for_reading = select(1, &input_set, NULL, NULL, &timeout); if(ready_for_reading) { char * returnCommand = Cmd_Debug_GetResponse(); printf("OK : %s\n", returnCommand); } else { printf("5 secs are over\n"); }时它正常工作，并且它的工作完全正如我想要运行。

但是当我调用网址api.subdomain.domain.com/admin时，我却遇到了错误。它适当地在当地开发和生产模式。只有API调用无效。

我使用了api.subdomain.domain.com/v1/products和ruby 2.2.2。

如果有人想了解有关此问题的详细信息，请与我们联系。

rails 4.2.3

我的routes.rb文件：

当我做rake路线然后我得到了这条路线

Rails.application.routes.draw do
  devise_for :admin_users, ActiveAdmin::Devise.config
  ActiveAdmin.routes(self)

  constraints :subdomain => 'api' do
    namespace :api, path: nil, defaults: {format: 'json'} do
      namespace :v1 do
        get "/products" => "products#all_details"
      end

      namespace :v2 do
        get "/products" => "products#all_details"
      end
    end
  end
end

我找到了解决方法。这里的问题是针对子域名的。这里我有2个子域和rails默认设置为TLD（Top Level Domain）。我用2增加了它，它为我工作。

这里将set 2作为值添加到production.rb

下面的配置中

config.action_dispatch.tld_length = 2

注意：实际上TLD不用于预子域，但它对我有用，所以我在这里给出了解决方案。它用于.com，.co.in ..

在亚马逊EC2生产中，ActionController :: RoutingError（没有路由匹配[GET]）
